Ok...first of all, use itkOriented Image instead of itkImage if you 
haven't done that already. By using itk::OrientedImage, index to 
physical coordinate
system transformation will take into account the direction cosines.

But, then I am not sure what you meant by reslicing the volume using 
direction cosines..

if you would like to reslice an orthogonal plane, you can use 
itk::ExtractImageFilter but if you would like to reslice an oblique 
plane, you can use itk::ResampleImageFilter...
